We study the time-varying efficiency of 15 Middle East and North African (MENA) stock markets by generalized Hurst exponent analysis of daily data with a rolling window technique. The study covers a time period of six years from January 2007 to December 2012. The results reveal that all MENA...

This paper proposes a new efficiency index to model time-varying inefficiency in stock markets. We focus on European stock markets and show that they have different degrees of time-varying efficiency. We observe that the 2008 global financial crisis has had an adverse effect on almost all EU...

We analyze the cross-correlation matrix C of the index returns of the main financial markets after the 2008 crisis using methods of random matrix theory. We test the eigenvalues of C for universal properties of random matrices and find that the majority of the cross-correlation coefficients...

The aim of this paper is to obtain some statistical properties about runs of daily returns of ISE30, ISE50 and ISE100 indices and compare these results with the empirical stylized facts of developed stock markets. In this manner, all time historical daily closing values of these indices are...

This article proposes a new procedure to evaluate Asia Pacific stock market interconnections using a dynamic setting. Dynamic Spanning Trees (DST) are constructed using an ARMA-FIEGARCH-cDCC process. The main results show that: 1. The DST significantly shrinks over time; 2. Hong Kong is found to...

This paper applies cDCC model to compare the dynamic correlations between oil prices and exchange rates of G20 members. The significant shifts in the correlations are then endogenously detected. For each pair of oil price-exchange rate, empirical evidence confirms of a strengthening negative...

This study analyzes the dynamic relationship between exchange rate (against US dollar), interest rate and the stock market (both in local currency) of Turkey from January 2003 to September 2013. In particular, the paper tries to answer if the correlations between these important variables change...

Using DCC-MIDAS model, we estimate the time-varying long-run correlations between crude oil and the major asset classes; then the structural changes in these correlations are determined with various methodologies. We reveal a strong positive (negative) secular trend toward higher correlation...

Using dynamic conditional correlations and networks, we bring a novel framework to define the integration and segmentation of emerging countries. The individual EMBI+ spreads of 13 emerging countries from 01/2003 to 12/2013 are used to compare their interaction structure before (phase 1) and...

We focus on the developments in the EMU sovereign debt markets in the last decade. First, we show the integration structure of the EMU bond markets before and after the sovereign debt crisis. Accordingly, a fair integration is observed between EMU bond markets during the pre-crisis period....
